UNITED STATES WILLIAM R. OSTRANDER, OF NEW YORK, N. Y.

SPEAKING-TUBE MOUTH-PIECE AND BELL-LEVER.

SPECIFICATION forming part of Letters Patent No. 235,285, dated December7, 1880,

Application filed October 16, 1880.

To all whom it may concern:

Be it known that 1, WILLIAM It. Os'rRAN- DER, of the city, county, andState of New York, have invented a new and Improved Speaking-TubeMouth-Piece and Bell-Lever; and I do hereby declare that the followingis a full, clear, and exact description of the same.

The speaking-tubes and levers for operating bell-wires in dwellings havebeen heretofore arranged as parts of distinct or separate apparatus. Itis the object of my invention to combine them in one, and thus effect aneconomy in construction of such apparatus, and also promote convenienceof communication between different rooms or apartments. To these ends Iarrange a bell-wire lever in connection with the mouth-piece of aspeaking-tube, so that they form one device or parts of one apparatus.

I show and describe, in connection with such mouth-piece and bell-lever,a shifting rosette and an annular frame, for which I pro pose to make aseparate application for Letters Patent.

The construction and combination of parts are as hereinafter set forth,reference being had to accompanying drawings, in which- Figure l is aface view of the complete device or apparatus embodying my invention, aportion being broken out. Fig. 2 is a view of rear side of the same.Fig. 3 is a section on line a; a, Fig. 1. Fig. at is a perspective viewof the bell-lever detached. Figs. 5 and 6 are, respectively, a plan andcross-section of the frame to which all the other parts are (inpractice) attached. Figs. 7 and S are, respectively, a plan or face viewand a crosssection of the shiftable rosette.

The letter A indicates a speaking-tube that may be supposed to extendfrom one room or apartment to another, or others between which it isdesired to establish vocal communication. Such tube is provided with amouth-piece, B, which is attached to a short exteriorly-threadedsection, a, ofgas-pipe or other suitable wroughtiron tubing.

0 is an annular frame that is secured by screws passing through holes 0to a block or stud (not shown) in the partition of buildingwall. TheframeOhas a base-piece, b, through which the tubular section a of themonth-piece passes, as shown.

PATENT OFFI (Model) The annular portion 9 of the bell-lever D fitsloosely into the circular space inclosed by the ring of frame G, and thesheet-metal rosette E rests on said frame, its pendent inner flange, d,being interposed between part 9 of the lever D and the frame.

The rosette E has a narrow segmental portion out out, as shown at c,Fig. 7, thus exposing a corresponding portion of frame 0. The uppershoulder of the cut-out portion of the rosette serves as a stop for thebell-lever. The screw f is inserted in such exposed part of frame 0 andprevents the rosette from moving to the left, Fig. 1, as the tension ofthe bell-spring tends to make it.

The rosette E maybe shifted one-quarter round to adapt the bell'lever Dto turn to the right or left. When the rosette is thus shifted thescrewfis inserted on the opposite side of the frame 0, and the bell wireor wires [1 are correspondingly shifted, and the frame C- also turned sothat its base part Z) will lie horizontally instead of vertically.

The mouth-piece B of the speaking-tube A is spun from sheet metal andsoldered to the pipe or tubular section a. Its exterior flange holds thebell-lever D and rosette E in place on frame 0, yet allows the requisitevibration of the former.

I thus combine in one device the monthpiece of a speaking-tube and thelever ot' abell or alarm, so that a servant or other person in the roomwhere the bell is located may be signaled and vocally communicated withwith the greatest convenience and dispatch.

The cost of the device and the labor, time, and expense of attaching itto the wall are likewise only about half as much as when the two partsare made and attached separately.

What I claim is- As an article of manufacture, a mouth-piece for aspeaking-tube and a bell-lever pivoted to or upon said mouth-piece, andadapted, substantially as shown and described, to be secured to the wallby the same attachment.

The above specification of my invention signed by me this 7th day ofOctober, 1880.

IVILLIAM It. OSTRANDER.
